This was a question sent by email . see my original basic deposition post here

Q: Thanks Brad. Looks like a good solution for this scenario where the spigots are in a straight line, but how would you go about doing a perimeter discharge (the most common type of TSF). The pathways and guidelines would be crossing over.

A: It’s a good question, I generally wanted to just show the basic concept in the original post. To do a perimeter discharge you just draw pathways coming back the other way and very roughly trim them up.

Here is how I would tackle it using the same method.

I start by making the one spigot discharge into a block. Then use the measure command to space it around the complex at 200m intervals. Align that block to the line and you get something like below.

 

I delete a few of the stranger spigots, relocate as necessary then I just keep trimming the lines inside the block until I get to a point where I don’t have too much overlap. Like below. (If I trim in the block, they all change at once. J)

Trim any major areas of overlap and then check your rough triangles surface, near enough is good enough here, minor overlap will be taken care of by the kriging routine,

Now just krig and trim, not a bad result I think?
